How did european countries and the united states explain and justify their invasion and conquest of extensive overseas territories in the late nineteenth century

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

European countries and the United States explained and justified their invasion and conquest of extensive overseas territories in the late nineteenth century in that these world superpowers believed that they had to establish control and dominion abroad in some territories for strategic purposes that can be translated into economic and political interests in different regions of the world.

One of the clearest examples is the "Scramble for Africa." At the end of the 1800s and the beginning of the 1900s, European powers split the African continent in order to establish colonies that created new territories. But what these countries such as France, Germany, Great Britain, or Portugal really wanted was to exploit the many raw materials and natural resources to produce goods in their industries and increase their profits.
